Ext3 problems

Hi, I received in my magazine (Linux Format, UK) a dvd copy of the FC2
release, and eagerly installed it.

Previously I had installed test3 of FC2, but it was unable to properly
read/write on my second hard drive:

[root@localhost root]# hdparm -i /dev/hdb
 
/dev/hdb:
 
 Model=SAMSUNG SP1604N, FwRev=TM100-23, SerialNo=0651J1FW881398

 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: (null):

Usage:

[root@localhost root]# df
Filesystem           1K-blocks      Used Available Use% Mounted on

/dev/hdb1            153834852  79450276  66570160  55% /mnt/home




It's a new(ish) ~200gig drive, I use to hold all of /home so that
upgrades are painless.

Anyway, when using FC2 test3, I couldn't use the drive at all really, so
gave up and fresh-installed FC1. This worked perfectly, and during all
my non FC2 time, the drive has worked 100% perfectly - never any data
loss or problems. I really do _not_ feel the disk is dying at all

Anyway, firing up FC2 and adjusting /etc/fstab to the following:

/dev/hdb1               /home                   auto defaults,noauto,rw
0 0

Anway, I created a user EdMack to match the uid and user-dir on the
drive, and logged in.

So, logging in fails. Here's a directory listing from
/home/edmond	(edmack's home dir.. I know..)

bash-2.05b$ ls -l
total 8
drwxr-xr-x   5 edmack 503 4096 Jul  3 13:37 Desktop
drwx------  10 edmack 503 4096 Jun 23 19:00 evolution
?---------   ? ?      ?      ?            ? fonts
?---------   ? ?      ?      ?            ? skype
?---------   ? ?      ?      ?            ? Templates

Trying to visit Templates (once a dir..)

bash-2.05b$ cd Templates
bash: cd: Templates: Input/output error

When trying to write a file:
[ Could not open file for writing: Read-only file system ]
(due to below..)

Here's the dmesg errors (many many times):

kjournald starting.  Commit interval 5 seconds
EXT3-fs warning (device hdb1): ext3_clear_journal_err: Filesystem error recorded from previous mount: IO failure
EXT3-fs warning (device hdb1): ext3_clear_journal_err: Marking fs in need of filesystem check.

Runnig badblocks -nsv gives me clear (didn't test 100% of disk)

Any information you need I'll try my best to obtain - please help :) I'm
kinda stuck here with no access to about 80gigs of personal data (I've
backed up to cds a lot, but nowhere near all - especially not my most
recent projects..) Any ingenious ways to back up about 80gigs in a home (I'm a student, no techie job) 
situation are greatly appreciated ;)

Anyway, Thank you very much for your time and efforts

Ed Mack
